gm mogrify -format foo preserves original?

The mogrify command currently preserves the original file if
'-format foo' is used to change the format of the file.  When the 
utility completes, there could be just one file (requested format is 
the same as the original) or two files (requested format differs).

This approach differs from other mogrify operations which always alter 
the input file.  Logically, it seems that '-format foo' should remove 
the original input file after a successful format conversion.  The 
current behavior is a bit odd, but if it is changed, it may cause 
problems for users since it is a change and they could lose files

Current operation:

% ls
crap.jpg save.jpeg
% gm mogrify -format jpeg *.*
% ls
crap.jpeg crap.jpg save.jpeg
